Publishing Linked Data is a process that involves many steps, design decisions and technologies. Some initial guidelines have been provided by Linked Data publishers, but these are still far from covering all the steps that are necessary. This chapter, from the book "Linking Government Data" (Springer, 2011), proposes a set of methodological guidelines for the activities involved in the publication process. These guidelines are the result of the authors' experience in the production of Linked Data in several Governmental contexts and are validated by the GeoLinkedData and AEMETLinkedData use cases.

- Chooses "hash"- or "slash"-based URI patterns based on requirements.
- Cleans a dataset by finding and correcting errors, removing duplicates and unwanted data.
- Generates RDF data from non-RDF sources.
- Recognizes that owl:sameAs, while popular as a mapping property, has strong formal semantics that can entail unintended inferences.
- Recognizes the desirability of a published namespace policy describing an institution's commitment to the persistence and semantic stability of important URIs.
- Understands trade-offs between "opaque" URIs and URIs using version numbers, server names, dates, application-specific file extensions, query strings or other obsoletable context.
- Reuses published properties and classes where available.
- Uses available resources for named entity recognition, extraction, and reconciliation.
